Abstract (en)
The present invention provides a method for separating a saturated fatty acid and an unsaturated fatty acid from a mixture of fatty acids by a dry fractionation process with a superior efficiency. Namely, the present invention provides a method for producing a saturated fatty acid or an unsaturated fatty acid comprising a dry fractionation process to fractionate a saturated fatty acid and an unsaturated fatty acid in a raw fatty acids mixture by adding a polyglycerol ester of fatty acid to the raw fatty acids mixture, wherein the polyglycerol ester of fatty acid has a clear melting point (y) satisfying the following formula (1): <DF NUM="(1)">0.38 x + 13 </= y </= 0.54 x + 44 </DF> wherein x is a ratio (% by mass) of saturated fatty acids (C12 to C22) in raw fatty acids, and y is a clear melting point ( DEG C) of a polyglycerol ester of fatty acid.
